A righteous king of the nation of Judah in the Old Testament. He reigned for twenty-nine years, during the time that Isaiah was the prophet in Judah (2 Kgs. 18–20; 2 Chr. 29–32; Isa. 36–39). Isaiah assisted him in reforming both church and state. He suppressed idolatry and reinstated the temple services. Hezekiah’s life was extended fifteen years through prayer and faith (2 Kgs. 20:1–7). The early part of his reign was prosperous, but his rebellion against the king of Assyria (2 Kgs. 18:7) resulted in two Assyrian invasions: the first is described in Isaiah 10:24–32, the second in 2 Kings 18:13–19:7. In the second invasion, Jerusalem was saved by an angel of the Lord (2 Kgs. 19:35).
